VALVE FOR GARMENT PRESSES Filed Aug. 27. 1931 INVENTOR Patented Dec. 13, 1932 UNITED STATES PATENT OFFICE WILLIAM A. ZEIDLER, OF BRONXVILLE, NEW YORK, ASSIGNOR TO THE UNITED STATES HOFFMAN MACHINERY CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE VALVE FOR GARMENT PRESSES Application filed August 27, 1931. Serial No. 559,698.

The object of my invention is to provide a valve for a garment press, although it may be used wherever suitable, which will be simple V and reliable in operation, and not leak or get L out of order. This and other objects are accomplished by my invention, one embodiment of which is hereinafter more particularly set forth. r For a more detailed description of my invention, reference is to be had to the accom panying drawing, forming a part hereof, in which Figure 1 is a longitudinal elevation of a valve embodying my invention; and

Figure 2 is a sectional view taken on the line 22 of Figure 1, looking in the direction of the arrows.

Throughout the various views of the drawing, similar reference characters designate similar parts.

My improved valve 1 is put in a head 2 in the conventional manner, and is held with a steam tight joint in its head by means of screw threads 3 at its lower end and a packing 4 held by a bushing 5 just above the head so that the packing is pressed against the upper surface of the same. The interior of the head is supplied with live steam at all times. From time to time it is desirable that this live steam be injected into the fabric of the garment, and this is accomplished by permitting steam to escape from the mouth 6 of the valve. The means for permitting this will now be set forth.

The main tube 7 of the valve body 1 has a port 8 at its side and this is connected to a small tube 9 running upwardly and enlarged at its upper end, so as to have a chamber 10 in which is placed a floating valve 11. This 4 0 I I q fioatmg valve has a conlcal surface which is adapted to seat against a seat 12 held in place by a cap 13 with a central bore '14 through which the stem of the valve 11 is passed. The lower portion of the valve 11 is given any suitable shape but is preferably made as shown and is substantially square in cross section. Outside of the tube 9 is a chamber 15 into which passes thelower end of a cap 16 which is large enough to enclose the cap 13 id but the space between these caps is not great so that steam which passes therethrough will be jetted for a purpose which will be mentioned below. The cap 16 has a loose sliding fit in the tube 7, so that this cap moves easily. The topof the cap has a rounded surface 17 adapted to be engaged by a lever 18 fulcrumed at 19 in a bracket 20 that rises from the tube 7, and rests on a suitable collar 21, and this bracket 20 has another arm which guides this lever 18, and the bracket is held by means of a bushing 22, as indicated. On top of the tube 7 and under the protecting flange of the cap 17 is a coil spring 28 against which the cap 16 is shifted when pressed by the lever 18.

Operation In view of the foregoing, the operation of my improved valve will be readily understood. Let it be assumed that live steam or any other fluid enters through the port 8 and presses against the floating valve 11 and holds the same to its seat against the seat 12. As long as this condition exists, there is no leak- I age and no escape. of live steam through the mouth 6. When such an escape is de sired, a light pressure is brought on the free end of the lever 18 and thereupon the cap 16 is depressed against the tension of the spring 23, untilthe top 17 engages the floating valve 11 and lowers-it from its seat. As soon as this occurs, steam rushes through the port 8, about the valve 11, into the interior of the cap 16 and then it is jetted downwardly because of the small opening be tween the caps 18 and 16, by the lower edge of the cap 16, and thence out through the mouth 6, so that the steam is distributed in the conventional manner. Assoon as this steam is jetted in this way, there is a suction about the exterior of the cap 16. and a small amount of air is drawn into the valve and about this cap, but not enough to, in any way, interfere with the functioning of the apparatus. However, enough has been drawn to make an exterior to interior flow about the cap so that there is no leakage of steam into the room where the press is being operated. The instant the pressure on the free end of the lever 18 is released, the

spring 23 restores the lever to normal, the top edge of the lever resting against a suitable part of the guide 20, as indicated, and the floating valve 11 then comes to its seat against the packing 12 and makes a tight joint so that the apparatus is-ready for another operation.

While I have shown and described one embodiment of my invention,it isobvious that. it is not restricted thereto, butthat it is, broad enough to cover all structures that come Within the scope of the annexed claims.

Having thus described my invention, What I claim is:

1. In a device of the class described, a valve bodywith an interior port,- a floating valve in said port, which is adapted to be normally kept closed'by fluid pressure in the port, a cap surrounding said floating valve and partially surrounding the port in which it func tion's, and means for forcing the cap against th'efloating valvewhereby the same may be opened. 1 I

2. In a deviceof the class described, a valve body having a port With a floating'valve at one end thereof, the parts being so arranged and disposed-that fluid pressure inthe port willclose the floating valve, acap surrounding the said port and floating valve, a spring normally keeping said cap raisedand means for depressing thevcap against the tension of the spring whereby the floating valve is engaged by the cap andopened andfluid allowed to pass through the port.v

8. In a device of the class described, a valve body having a port, a floating valve adapted to close said port, a cap surrounding said floating valve and said'port,.a tubular part of the valve body partially surrounding saidlcap, and means fordepressingthe cap against the floating valve so as to open the same, and means for causing fluid adapted to flow through the port to jet throughthe interior of the cap whereby a suction fronithe exterior to the interior between-said cap and tubular part is providedand leakage is prevented.

4:. In a device of the class described, a valve body having a port, a floating valve adapted to close the port when under fluid pressure, and means surrounded by the valve body and surrounding said port and said valve for causing an exterior to interior suction when pressed against the floating valve to open the same.

Intestim'ony whereof, I have hereunto set my hand this 25th day of June, 1931.
